Application January 27, 1934, Serial No. 708,587

Our present invention relates to improvements in weather stripping for sliding window sashes and particularly to weather stripping of the resilient slidably interlocked type.

It is an object of our invention to provide a simple and inexpensive form of weather stripping for the vertical edges of sliding window sashes capable of self adjustment to compensate for poor fit of sashes in their frames and changes in the fit caused by shrinkage of the sashes or frames.

Another object is to provide such weather stripping wherein self-adjustment thereof eliminates binding, sticking and distortion of parts thereof when the clearance between the sash and frame to which the same is applied has been changed due to shrinkage or other causes.

Still another object is to provide such a form of weather stripping wherein one member thereof attached to a sash, another member thereof attached to a frame, and a still other member having a tongue engaged in a groove in the frame cooperate to prevent passage of air between the sash and the frame regardless of shrinkage of the sash or frame.

Yet another object is to provide such weather strip construction whereby a sash will be resiliently guided in its frame and restrained from rattling.

A further object is to provide such'weather stripping which is simple and inexpensive of manufacture and which may be easily and readily applied to sashes and frames of conventional commercial types.

These and other objects and advantages of the invention will be more fully set forth in the following description made in connection with the accompanying drawing, in which like reference characters refer to similar parts throughout the several views, and in which:-

Fig. l is a perspective view of a section of our improved Weather stripping;

Fig. 2 is a horizontal sectional view of portions of a conventional window sash and frame with the weather stripping of Fig. 1 applied thereto, and

Fig. 3 is a horizontal sectional view of portions of a conventional window sash and frame with a slightly modified form of our weather stripping applied thereto.

Referring. to the drawing, it will be seen that the embodiments of our invention shown are applied to a conventional window frame and sash including a vertical frame side 4, a stop 5, a moulding. 5a, a vertical sash stile 6 and a glass pane 'I held in the sash by means of a putty fillet 8. f

Our weather stripping includes a stationary strip S secured to the frame side 4 and a strip M secured to and movable with the sash stile 6, 5

these strips being connected together in interlocked relation but being free for relative longitudinal sliding movement. A floating angle shaped strip F is also included and is retained as will be described. These three strips are constructed of thin resilient sheet material such as spring bronze or similar materials.

In the following description outwardly and inwardly are to be construed as respectively meaning toward the exterior and toward the interior of the building in which the sash and frame are installed.

Referring particularly to Figs. 1 and 2, a relatively wide strip of sheet material comprising the stationary strip S, is so formed as to have a main section 9 which is flat except for corrugations 9a formed therein. The inner edge of the main section 9 is secured to the frame side 4 by nails Ill driven through suitable apertures I I in the main section 9 into the frame side 4 along a line dis- 25 posed inwardly of and parallel to the outer side of the sashstile 6. The line referred to should preferably be located inwardly of the sash stile 6 as indicated in the drawing. Y Y

At the outer or free edge of the main section 9, the stationary strip S is bent upon itself to produce a section I2 formed integrally with and extending from the free edge of the main section 9 parallel to and in closely spaced relation with the outer portion of the main section 9. A second and oppositely turned bend is made in the stationary strip S to provide a third section I3 lying parallel to and somewhat spaced from the strip I2 as shown. A right angled bend is made in the stationary strip S to form a fourth section I4 extending toward the sash substantially in the plane of the outer side of the sash. Another bend is made in the stationary strip S to provide a fth section I5 lying inwardly of the section I4 in parallel spaced relation thereto and extending toward the main section 9. One leg Ilia of a floating strip F which has been bent at right angles substatially along its longitudinal center line, is placed between the sections I2 and I3 of the movable strip M to be slidably retained therebetween, the remaining leg I6 constituting a tongue projecting in a direction away from the sash stile 6. A groove I6b is formed in the frame sidel 4 adjacent the stop 5 to receive the tongue 'I 6. The

groove Ib is of such widthA as to permit'free 55.

movement of the tongue I6 with respect to the sides thereof.

The movable strip M of our weather stripping consists of a strip of sheet material bent along longitudinal lines to form a portion comprising spaced parallel sections I'I and I8 and having a bead I'Ia at the free edge of the section I l, an attachment section I9 and a diagonally disposed section 20 connecting the section I8 to the attachment section I9 in inwardly oiset parallel relation thereto, as shown. The vertical sash stile 6 is rabbeted at its outer corner to receive the sections Il and I8 and the bead Ila of the movable strip M and is further rabbeted to receive the attachment section I9 of the movable strip M which is secured to the stile by nails 2I or other suitable means. The sections I4 and I5 of the stationary strip S and the sections I'I and I8 of the movable strip M are connected together in interlocked but relatively slidable relation by disposing the section I5 of the stationary strip S between the sections I'I and IS of the movable strip M and the section Il of the movable strip M between the sections I4 and I5 of the stationary strip S, as shown. The sections I4 and I5 of the stationary strip S comprise Ya guide for the section I1 and bead I'Ia of the movable strip M. The various sections comprising the stationary, movable and floating strips S, M` and F are so proportioned and arranged respectively that the outer sides of the sections I4, I6 and I9 lie substantially in the same plane as the outer side of the sash stile 6.

It will be seen that the interlocked sections I4, I5, Il and I8 cooperate to oier an obstacle to the passage of air and moisture between the sash stile 6 and the stationary strip S and that contact of the section I3 and the corrugations 9a with the stile 6 offer further obstacles. The tongue I6 of the oating strip F in cooperation with the groove Ib and the section 9 of the stationary strip S, at its point of attachment to the frame side 4, prevent passage of air and moisture between stationary strip S and the frame side 4. Contact of the section I4 of the stationary strip S with the stop 5 also assists in preventing passage of air and moisture. Also, since Ythe resilient stationary strip S is secured to the frame side 4 only at its inner edge and the tongue I 6 ofthe floating strip F is movably engaged in the groove i612, it is clear that the main section Q of the stationary strip S is free to ex if and when shrinkage of the sash or frame takes place, thus preventing distortion of the interlocked sections I4, I5, I 'I and I8 and permitting the same to remain in their normal positions relative to each other and to slide with respect to each other without binding or sticking. The corrugations 9a in the main section 9 of the stationary strip S improve the ilexibility of the main section 9 as well as providing for Contact of portions of the main section 9 with the sash stile 6. The corrugations 9a also constitute resilient guides for maintaining the sash in centered relation to the frame. It is to be noted that the arrangement of the interlocked sections I5, I5, I'I and I8 of the stationary and movable strips S and M is such that the outer portions of the stationary strip S Will be drawn away from the frame side I with the movable strip M Whenever the spacing between the sash stile 6 and the frame side i is increased due to shrinkage of the sash or frame or any other cause.

The bead I 'Ia facilitates smooth slidingr of the movable strip M withjrespect to the stationary strip S and also assists in the formation of an effective seal between the strips S and M.

In the installation of our weather stripping on a sliding window sash and frameVthe moulding 5a and the sash are rst removed from the frame and the vertical stiles of the sash are rabbeted as previously described and the groove Ib is formed in the frame side 4. The stationary and movable strips S and M are assembled in the relation shown in the drawing and previously described and the attachment section I9 of the movable strip M is attached to the sash stile t. The oating strip F is placed in its normal position as shown in the drawing with the leg I 6a thereof in position to be subsequently received between the sections I2 and I3 of the stationary strip S. Next,v

the sash, with the stationary and movable strips S and M attached is placed in the frame in its normal position and the leg I 6a of the floating strip F is received between the sections I2 and I3 of the stationary strip S. The nails IS are then driven and the moulding 5a is secured in place; If it is later desired to remove the sash from the frame, as for replacement of a broken window pane therein or other purposes, removal of the moulding 5a and extraction of the nails I0 is all that is necessary lto release the sash and our weather stripping for such removal.

Referring particularly to Fig` 3, it will be seen that the stationary strip T, the movable strip N corrugations 22a therein, the nails 23, the sections 2d. and 25, the floating strip G and the groove 2l, respectively, correspond to and areidentical with the main section 9, thecorrugations 9a, the nails IB, the sections I2 and I3, the floating strip F and the groove 16h of the form of weather stripping shown in Figs. 1 and 2 and described above` At the outer edge of the section 25 of the stationary strip T a right angled bend is made to provide a section 27 extending toward the sash stile 6 and lying substantially in the same plane as the outerV side of the stile 6. Another rightangled bend is made toward the inner side of the sash stile 6 forming a section 28 disposed substantially parallel to the main section 22. Another right angled bend is made toward the main section 22 and still another right angled bend is made toward the outer side of the sash to successively form a section 29 disposed at right angles and a section 30 disposed parallel to the main section 22. A bead 36a is formed at the free edge of thesection 30.

The movable strip N is bent at right angles to form an attachment section 3| and a section 32 extending toward the inner side of the stile 6 in substantially parallel relation to the main section 22 of the stationary strip T. Another right angled bend is made toward the stationary strip T to produce a section 33 disposed at right angles to the stationary strip T and still another right angled bend is made to produce a section 34 extending tovvard the outer side of therstile 6 substantially parallel to the section 32. Two more right angled bends are made to successively form a section 35 extending away from the stationary strip T at right angles thereto and another section 36 extending toward the inner side of the sash stile 6 parallel to the stationary strip T. y A bead 36a is formed at the .free edge of the section as.

to receive the movable strip N and the attachment section of the movable strip is secured to the stile 6 by the nails 31 or other suitable means.

The movable strip N is connected to the stationary strip T in interlocked yet relatively slidable relation thereto by disposing the section 36 of the movable strip N between the sections 28 and 3U of the stationary strip T and the section 30 of the stationary strip between the sections 34 and 36 of the movable strip N.

The various sections o the stationary strip T and the movable strip N are so proportioned and arranged that the outer sides of the sections 26, 21 and 3| are all disposed substantially in the same plane as the outer side of the sash stile 6.

It is apparent that we have invented a novel, rugged, simple, inexpensive and eiective form of weather stripping, capable of self-adjustment to compensate for changes in the clearance between the sash and its frame, such as occasioned by shrinking, sagging and other causes.

It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of the parts, without departing from the scope of our invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, and in the novel parts and combinations of parts disclosed and dened in the appended claim.
